Bright Orange Chlorine Test Results - Damaging?

Have the same problem. Pool store man says don't worry about it. Been that way for two weeks. I have stopped using the 3" clorine tabs and will discontinue shocking once a week until this situation clears up. I have a 10K pool and I dont use liquid chlorine just one shock packet once a week and two 3" tablets.

I too have chlorine readings off the scale! over 5ppm! This is true with three new different tert kits (oto and ph drop test). I too have confirmed via test strips and my local pool store that the chlorine level is correct. I have my pool in perfect balance (18,000 gal. vinyl liner). So....why are the test kits not accurate? I have shocked my pool when opened as directed by my pool store with bioguard, 6 pounds. Thanks! Who am I ? Google "adobekid1"

The test kits are probably right, at least for order-of-magnitude of you having high chlorine levels. I don't know which BioGuard product you used for shocking, but if it was BioGuard® Smart Shock® , then that is about 63% Dichlor (anhydrous so equivalent to 73% Dichlor dihydrate -- normal Dichlor product is 99% Dichlor dihydrate) PLUS some copper as well as clarifier, flocculant, etc. Anyway, 6 pounds of this product in 18,000 gallons would probably raise the FC by 16 ppm and also increase CYA by 15 ppm. So there is no mystery here, but I suggest you read the Pool School and get yourself a proper test kit if you want to properly manage your pool. Following pool store advice will likely cost you a lot more.

Anyway, that chlorine level will not damage your vinyl because you also added CYA to the water, via the Dichlor. CYA significantly moderates chlorine's strength. It would, however, be a problem if you dumped it in one place and had it settle to the bottom of the pool. When adding most concentrated chemicals, you should add them slowly over a return flow with the pump running, preferably in the deep end, and then lightly brush the side and bottom of the pool where you've added the chemical to ensure thorough mixing.

Hello,
I picked this thread out of the ether!! I have a similar problem here in Spain with regards to my outdoor pool water OTO test results showing Dark Orange. Weather over the last couple of months has been very, very cold with faint, insignificant sunshine.

Because I thought it necessary, on return from holiday (2 mths), I added chlorine cryatal to pool, without first checking reading!!! Since return I have not been able to sort out thes Orange Test problem. Have tried by adding copious amounts of PH + powder..............as you can tell I know nothing about this chemical balancing of the pool.Be grateful for any advice guidance you can give.

Thank you for your time..................David Castle

The orange OTO test means that you have a very high chlorine level in the pool. You can add a chlorine neutralizer product to reduce the chlorine level. pH adjustment isn't going to fix this problem.

If you can't find any chlorine neutralizer at a pool store, you can use hydrogen peroxide for that purpose, preferably a concentrated form of it. Even if you only find 3% hydrogen peroxide, one volume of it will neutralize an equal volume of 6% bleach so 1 gallon of 3% hydrogen peroxide will neutralize around 6 ppm Free Chlorine (FC) in 10,000 gallons of pool water. Obviously, if you can find 27% hydrogen peroxide then you'll only need to use 1/9th as much.

Thank you VERY much for the info. My trouble now is to find out the equivelant to a Chlorine neautralizer or Hydrogen Peroxide..in Spanish!! Will keep you posted. Again, thank tou...David Castle :crazy:
Too Much Chlorine

Okay, so I tested this morning and my home kit showed about 3 ppm chlorine and a PH of roughly 7.8. Okay so no problem right? I added water to bring the chlorine down a bit as the pool was a bit low anyways. So...next test PH is up above 8 (okay, could be due to the additional city water) but now my chlorine test is showing bright orange.

This is counter intuitive to me. I get the PH reading, kinda, but can't imagine how my Chlorine level went up after I raised the water level in the pool by at least an inch, maybe an inch and 1/2. Any thoughts?

That is bizarre. Are you talking about the 5-drop OTO chlorine test or are you talking about test strips?

I am using an Aquarius 4 drop kit. I am going to try the strips and see. I think the kit is flawed.
